AI Article Synopsis
- Fanconi anemia (FA) is a rare genetic disorder with 15 subtypes, and most cases are linked to mutations in the FANCA gene.
- A study of 166 patients suspected of having FA found that 13 were diagnosed, with 62% (8 patients) belonging to the FA-A subtype.
- Researchers identified a novel point mutation in exon 26 of the FANCA gene, marking its first documentation in this context.
Article Abstract
Background: Fanconi anemia (FA) is a rare genetic disease characterized by considerable heterogeneity. Fifteen subtypes are currently recognised and deletions of the Fanconi anemia complementation group A (FANCA) gene account for more than 65% of FA cases. We report on the results from a cohort of 166 patients referred to the Department of Medical Genetics of Athens University for genetic investigation after the clinical suspicion of FA.
Materials And Methods: For clastogen-induced chromosome damage, cultures were set up with the addition of mitomycin C (MMC) and diepoxybutane (DEB), respectively. Following a positive cytogenetic result, molecular analysis was performed to allow identification of causative mutations in the FANCA gene.
Results: A total of 13/166 patients were diagnosed with FA and 8/13 belonged to the FA-A subtype. A novel point mutation was identified in exon 26 of FANCA gene.
Conclusion: In our study 62% of FA patients were classified in the FA-A subtype and a point mutation in exon 26 was noted for the first time.
